On a heat pump repair call in Beauregard Parish, a contractor looks at the reversing valve and the defrost controls before anything else. Homes in Beauregard Parish, LA run heat about five months a year, from November through March. Across that stretch of cold-side running, the reversing valve cycles between heating and cooling mode every time the outdoor coil ices, and the defrost board decides when that switch happens. Both parts wear through repeated switching under load, not through age sitting in a garage. When one gives out, the system either locks into one mode or drops capacity sharply, which is how most repair calls here begin.
Half the homes in Beauregard Parish, Louisiana were built in 1992 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that age has likely been the second or third system those walls have held, and each swap leaves the original wiring and ductwork in place. When a contractor opens the unit, what they find in the refrigerant circuit or the reversing valve often depends on which generation of equipment is actually in there, and whether the parts that unit takes are still in supply. That answer comes from inside the system, not from the permit date.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and the outdoor coil. The compressor is the part that does the heaviest work, so it is often where a contractor starts when the system is not heating or cooling properly. The outdoor coil, the fan motor, and the refrigerant lines that connect to it are all examined early.
Inside the house, the air handler holds the indoor coil and the blower motor that moves conditioned air through the home. The reversing valve, which is specific to heat pumps and controls the direction of heat flow, sits in the refrigerant circuit and is a common source of trouble when the system heats on one mode but not the other. The expansion valve and the refrigerant lines that run between the two units are checked alongside these.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and need attention in your specific home.
